not for heavy duty tires!

December 19, 2011
i bought this and the first night i used it i went through 5 blades breaking them because the iron wouldnt get hot enough to cut through my super swampers..... then the blades started cut into the head. next the handle started to bend and fall apart from the rest of the iron.. i didnt even get through 3 treads and it fell apart..... not a good tool in my opinion...
No, I would not recommend this product.

Merchant Response:

After this customer notified us of the issue with the iron, we promptly sent him our heavy duty grooving iron # 445251 as a replacement, which will work better on harder tread compounds.

Great product, easy to use.

Don't forget to order the head and blades that are sold separately. Once this tool heats up, the grooving is fast and easy. It works well at the track powered by a 4k watt generator
Yes, I recommend this product.
